PRIORITY UNDER 35 U.S.C SECTION 119(e) & 37 C.F.R. SECTION 1.78

This nonprovisional application claims priority based upon the following prior United States Provisional Patent Application entitled: Foot Support Device, Application No. 61/882,659 filed Sep. 26, 2013, in the name of Uganda Williams, which is hereby incorporated by reference for all purposes.

FIELD OF THE INVENTION

The present invention relates generally to orthopedics, more specifically but not by way of limitation, an orthopedic shoe insert operable to be worn like a sock configured to provide enhanced support for the users foot. The orthopedic shoe insert includes an upper portion and a lower portion wherein the upper portion is stretchable and the lower portion includes a plurality of layers including but not limited to foam, gel and nylon spandex.

BACKGROUND

Millions of individuals experience some type of foot pain on a regular basis. Conditions such as but not limited to plantar fasciitis and other foot related ailments can be caused by various conditions and/or shoe types. Those individuals that spend a great deal of time on their feet for work often suffer from the aforementioned conditions which can create significant hardships and discomfort making it difficult to perform certain activities. It has been further shown that women have almost four times the chance of having some foot pain condition than men. A significant portion of this can be attributed to the shoe styles that women often wear such as but not limited to high heels.

One problem with existing foot pain treatment devices is they do not surroundably mount to the foot. Existing technologies such as but not limited to shoe insoles are typically placed within a shoe so as to reduce the impact pressure caused by walking or running. The insoles are typically manufactured from foam or a gel and superposed the interior surface of the sole of the shoe. There are several drawbacks to this design. First the only time the foot pain treatment device can be used is during the wearing of the particular pair of shoes in which the insole has been inserted. As many people routinely change shoes for different occasions, this requires that the user either purchase a set of insoles for each pair of shoes they intend to wear or transfer the insoles to the shoes that need to be worn by the user. The aforementioned options are both costly and/or inconvenient.

Another issue with existing shoe insoles (or inserts) are their impact on the fit of the shoe. Many insoles designs are manufactured from a gel or similar material and have a negative effect on the fit and comfort of the shoe. Subsequent to inserting the insole, the interior surface of the sole is effectively raised which can cause pressure on the upper portion of the foot resulting from the upper portion of the shoe being biased thereagainst with more force than when the insole is not in place.

Accordingly, there is a need for a foot support device that can be worn within a shoe that does not impact the overall fit of the shoe and further wherein the foot support device surroundably mounts the foot and can be worn without the need of a shoe.

DETAILED DESCRIPTION

Referring now to the drawings submitted herewith, wherein various elements depicted therein are not necessarily drawn to scale and wherein through the views and figures like elements are referenced with identical reference numerals, there is illustrated a foot support shoe insert 100 constructed according to the principles of the present invention.

Referring in particular to FIG. 3, a diagrammatic view of the layers of the sole 10 are illustrated therein. The sole 10 includes a bottom layer 12 that is operable to engage either the inside upper surface of the sole of an exemplary shoe. The bottom layer 12 is manufactured from a suitable durable absorbing material such as but not limited to gel. The gel material of the bottom layer 12 functions to provide the first layer of impact force reduction to the foot of the user disposed within the foot support shoe insert 100. Disposed on the bottom layer 12 on the external surface thereof is a gripping agent 14. The gripping agent 14 is operable to provide an increased coefficient of friction between the foot support shoe insert 100 and the shoe in which it is disposed. During rapid movements such as those made in a basketball game or other sports, there are significant lateral forces on the feet of an individual. Utilizing a gripping agent 14 on the outer surface of the bottom layer 12 provides additional securement of the foot support shoe insert 100 during movements of increased force. While no particular gripping agent 14 is required, good results have been achieved utilizing a nitrile rubber as the gripping agent 14. Additionally, utilization of nitrile rubber as the gripping agent 14 is desirable as nitrile rubber is less susceptible to bacteria growth. Those skilled in the art will recognize that numerous types of material could be utilized for the gripping agent 14.

Superposed the bottom layer 12 is a cushioning layer 16. The cushioning layer 16 is manufactured from a suitable durable material such as but not limited to memory foam. The cushioning layer 16 is secured to the bottom layer 12 utilizing suitable durable techniques such as but not limited to stitching and/or chemical adhesion. The cushioning layer 16 provides an additional layer of material within the sole 10 that provides impact force reduction. As the bottom layer 10 and cushioning layer 16 are manufactured from different materials have different cell structures, the bottom layer 10 and cushioning layer 16 combine to reduce impact force from walking or running more than a single layer of material. The cushioning layer 16 further includes magnets 20 disposed therein. The magnets 20 are conventional magnets and are manufactured in a circular shape being relatively thin. The magnets 20 function to stimulate acupuncture points on the foot disposed within the foot support shoe insert 100 in order to relieve muscle pain and similar symptoms. It is contemplated within the scope of the present invention that the magnets 20 could be present in numerous different quantities and placed in various locations. Additionally, it is further contemplated within the scope of the present invention that the magnets 20 could be manufactured in alternative sizes.

Superposed the cushioning layer 16 is protective layer 25. The protective layer 25 is manufactured from a suitable durable material such as but not limited to a polyurethane-polyurea copolymer. Those skilled in the art will recognize that such materials are spandex and lycra. The protective layer 25 is the upper surface of the sole 10 that will engage the foot of the user as a foot is disposed within the foot support shoe insert 100. The protective layer 25 is superposed the cushioning layer 16 and secured thereto utilizing suitable durable techniques such as but not limited to chemical adhesion and/or stitching. Utilization of spandex or similar material for the protective layer 25 is desirable as the elastic properties of the material provide the required performance for the user of the foot support shoe insert 100. This material or one similar thereto is further desirable as it has a porosity that allows airflow therethrough with is desirable for the foot support shoe insert 100 as further discussed herein. By way of example but not limitation, when a user participates in aggressive maneuvers, the elasticity of the protective layer 25 maintains the integrity of the material and prevents tearing or damage thereto. While not illustrated in particular herein, it is contemplated within the scope of the present invention that the protective layer 25 could be disposed completely around the cushioning layer 16 as an alternative to being superposed thereon. This configuration would provide protection for the cushioning layer 16 wherein the cushioning layer 16 is manufactured from an open cell foam.

As shown in FIGS. 3 and 4, the sole 10 includes a plurality of apertures 30 bored therethrough. The apertures 30 journal through the bottom layer 12 and the foam layer 16 but do not journal through the protective layer 25. In the preferred embodiment there are three apertures 30 in the sole and a fourth aperture in the heel cup 40. This configuration facilitates desired airflow into the interior of the foot support shoe insert 100 so as to reduce perspiration and increase comfort to the user. Apertures 30 located only in the sole 10 do not provide the air circulation required for desired performance and thus at least one aperture 30 is required in the heel cup 40. While a particular quantity of apertures 30 have been disclosed herein, it is contemplated within the scope of the present invention that the sole 10 could have numerous different amounts of apertures 30 journaled therethrough. Additionally, it is contemplated within the scope of the present invention that the apertures 30 could be manufactured in various different sizes.

Referring in particular to FIGS. 1 and 4, the heel cup 40 is illustrated therein. The heel cup 40 is integrally formed with the sole 10 and is operable to provide specific support and protection for the Achilles tendon of a user. The heel cup is manufactured from a dense foam material that is less resilient than that of the cushioning layer 16. It is contemplated within the scope of the present invention that the heel cup 40 could be manufactured from numerous different material in order to achieve the desired functionality herein. Located adjacent to the heel cup 40 is tab 50. The tab 50 is secured to the upper rear perimeter 55 utilizing suitable durable methods such as but not limited to chemical adhesion or stitching. The tab 50 is secured to the tab support 51. The tab 50 and tab support 51 are manufactured from a suitable durable material such as but not limited to nylon. The tab 50 provides an interface for a user to engage when donning the foot support shoe insert 100. The tab support 51 provides reinforcement and additional strength in the area that experiences additional pulling forces during the donning of the foot support shoe insert 100 by a user. Those skilled in the art will recognize that the tab 50 and tab support 51 could be manufactured in alternative styles and sizes.

Referring in particular to FIG. 2, a diagrammatic view of the upper inner surface 60 of the sole 10 is illustrated therein. As previously described herein, the protective layer 25 comprises the upper inner surface 60. Superposed on the upper inner surface 60 are a plurality of pads 70. The pads 70 are manufactured from a suitable material such as but not limited to gel or foam. The pads 70 function to provide additional cushioning for areas of a user's foot that experience more pressure during activities such as but not limited to walking or running. More specifically but not by way of limitation, the heel of a foot and the arch area are susceptible to greater stress and thus have pads 70 located proximate thereto. Certain areas of the foot are susceptible to higher force during the aforementioned activities. The pads 70 function to reduce the impact force transferred to the areas of the feet in which they are located. While three pads 70 have been illustrated herein of particular size and shape, it is contemplated within the scope of the present invention that the upper inner surface 60 could have numerous different sizes and quantities of pads 70 superposed thereon. The phalangeal joint supports 80 are further included on the upper inner surface 60. The phalangeal joint supports 80 are operable to fill the void 81 intermediate the upper inner surface 60 and the exemplary phalange 98. The human foot is shaped that the areas proximate the phalangeal joint are slightly higher than the bottom of the phalanges, in this example, the toes. This shape causes void 81 to be present between the phalangeal joint area and the surface on which a foot is superposed. This creates additional stress on these areas during activities such as prolonged standing, walking or running. The phalangeal joint supports 80 are specifically placed to be underneath each of the phalangeal joint areas of a human foot. This additional support substantially fills the void 81 and reduces the pressure on the phalangeal joint area. The phalangeal joint supports 80 are manufactured from a suitable material such as but not limited to gel or foam and are secured to the upper inner surface 60 utilizing suitable techniques.

Referring in particular to FIG. 5, a perspective external view of the foot support shoe insert 100 is illustrated therein. Proximate the first end 85 are the toe compartments 90. The toe compartments 90 are hollow having separate walls 92 defining each toe compartment 90. The toe compartments 90 function to provide a separate compartment for each toe of a human foot. While separate toe compartments 90 have been illustrated herein, it is contemplated within the scope of the present invention that the body 5 of the foot support shoe insert 100 could be manufactured having only one large toe compartment operable to receive but not separate all five toes of a human foot. The body 5 further includes an upper layer 7 that is operable to surroundably mount the upper portion 2 of an exemplary human foot 1. The upper layer 7 is integrally formed with the sole 10 and the sides 4 of the body 5. The upper layer 7 is manufactured from a suitable elastic material such as but not limited to spandex. An elastic material is desired for the upper layer 7 in order to facilitate improved donning of the foot support shoe insert 100. Furthermore, the upper layer 7 being manufactured from a material having some elasticity functions to ensure a secure and stable fit of the foot support shoe insert 100 reducing any movement once donned by a user. The upper layer 7 is formed to create opening 13. Opening 13 functions to provide access to the interior of the foot support shoe insert 100 in order to be donned by a user.

While not particularly illustrated herein, it is further contemplated within the scope of the present invention that the foot support shoe insert 100 could be manufactured such that it is calf height as opposed to the ankle height embodiment illustrated herein. Additionally, the foot support shoe insert 100 is contemplated having an embodiment that includes a compression element integrated therewith. The compression element would be secured to the body 5 and be operable to be surroundably mounted to a user's ankle and calf area for either additional support or to assist in treatment of symptoms of an injury. Furthermore, it is contemplated within the scope of the present invention that the compression element could extend beyond the ankle to an area such as but not limited to a user's upper thigh. While the gripping agent 14 of the bottom layer 12 has been taught herein to include an antibacterial function, it is further contemplated within the scope of the present invention that all other elements of the foot support shoe insert 100 could be impregnated with either anti-bacterial and/or anti-fungal material. Those skilled in the arts will recognize that numerous different compounds could be utilized for anti-bacterial and anti-fungal benefits.
